Question

In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice as : Assertion : Insulator do not allow flow of current through them Reason: Insulator have no free charge carriers * 1 point a)If both assertion and reason are true and reason is the correct explanation of assertion b)If both assertion and reason are true but reason is not the correct explanation of assertion c) If assertion is true but reason is false d)If both assertion and reason are false​

Answer 1

Answer:

A. If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.

Explanation:

In an insulator, the valance band is completely filled and the conduction band is completely empty. There is no charge carriers at all in the conduction band. Moreover as the energy gap Eg , where T is the room temperature, so no electron can jump from the valance band to the conduction band at low temperatures and even at higher temperatures.
